This is the most comprehensive Silver and Gold set, containing both Circulation Strikes and Proofs from their beginning in 1986 to the present. With about 320 coins it is topped by the scarce 1995-W Silver Eagle Proof, but the 1999-W $5 and $10 Uncirculated strikes aren't far behind. Although most of the rest of the coins are fairly common, bear in mind that at current prices this set melts for about $140,000. With premiums and certification, this set will probably require at least $250,000 to complete.
